I'd look into the spring-over conversion. You have to have new spring pads welded on top of the axles to maintain proper camber. You can't just flip the axles (unless they have no camber arch to begin with). Still a simple job and it will solve the problem once and for all. The height increase will be the axle diameter plus the spring thickness plus 2X the height of the mounting pad. Usually about 5".
